Early in his astrological career, John Townley introduced the composite chart technique for analyzing relationships in his book The Composite Chart, and 20 years later wrote the definitive work on the subject, Composite Charts: The Astrology of Relationships. He has pioneered techniques for astrological cycle analysis and proposed a new, physical basis for astrology. He is also the author of Planets in Love, Dynamic Astrology, and Lunar Returns, has been the president of the Astrologers' Guild of America, was the editor of The Astrological Review, and is a contributor to professional and popular astrological magazines. His books have been translated into seven languages.

John is also a well-known journalist, elected member of the American Society of Journalists and Authors, historian, preservationist, performer, and record producer. He can be regularly found, camera and microphone in hand, covering cultural and technological events ranging from the Consumer Electronics Show to the Toy Fair, from international music festivals to ocean sailing races. When he's not behind the camera and microphone, he's in front of them, performing at maritime concerts in the U.S. and across Europe.
